(No model.)

To all whom it` many cowcrn:

Be it known that we, ROBERT STEEL and J ONATHAN VANNOTE, citizens of theUnited States, residing at Philadelphia in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulIniprovements in Sprin '-Motors, of which the following is aspecification.

Our invention consists of the combination of a train of gear-wheels andpinions upon two shafts arranged in the same Vertical plane, that areactuatcd by the force inparted thereto by the resilieney of a series ofcoiled springs, (the inner end of each spring being perrnanentlyconnected to its arbor fast on the shaft to which it is attached, theresilient end being fast to the casc,) which are wound down elosely toobtain tensional force by a second series of fast and loose geauwheelsand pinions gearng together upon the opposite ends of the shafts towhich the driving-train is at tached, a third short shaft and its pinionand crank serving to give rotary motion to the aboVe-nientioned trainof'winding-gearing. The nechanisni for winding the coiled springs andthe train of wheels through which motion is imparted are containedwithin a case attached to the under side of a table of a sewing-machine,or to any convenient point of the machincry which it is desired torotatc.

The object of this invention is to provide a simple compact motoradapted to be used for the propulsion of sewing-machines and other lightmachinery. i

In the acconipanying drawings, which make a part of this specification,Figure 1 is a plan View of our improved apparatus. Fig. 2 is across-section taken at the line a b of Fig. 1. Fig. 3 is a like viewtaken at the line c d of Fg. 1. Fig. et is a side elevation with thefront of the case A removed.

Like letters of reference in all the figures indicate the same parts.

A is the metallc case, containing the apparatus, in the ends x x ofwhich the drivingshafts B B' have their bearings. B is the upper shaft;B', the lower. The shaft B is provided with the toothed wheelsC C O andtheir respective pinions b b'b' into which the like wheels C C* O gearby the pinions 6 b: The gear-wheels and their respective pinions areloose, and revolve upon the shafts to which they are attached. The onlywheel which is fast on the shaft (connected to the train ofdriving-gear) is the ratchet-wheel D, whose pawls d d are attached tothe gear-wheel C on the shaft B' by means of the pins e e. springs f fretain the pawls d in connection with the wheel C. (Seen clearly in Fig.2.) On the opposite ends of the shafts B B', to which the train ofoperating-gearing is connected, is the train of winding gear-wheelsfirst, the toothed wheel E and pinion g, attached thereto, and the wheelE all revolving freely on the shaft B'. On the shaft B is the gear-wheelE and its pinion g'. Into said wheel the pinion (1 on the shaft B'gears, which in turn imparts niotion to the wheel F', which is fast onthe shaft. wheel F' moton is nparted to the wheel F,

The

From said fast on the shaft LB', by means of which motion is imparted tosaid shaft..

G are the coiled springs, an equal number of which are fastened at theirinner ends to the arbors I on the shafts B B' by means of bolts h theouter ends of said springs being Secured to the sides y y of the case Aby means of bolts h'. Gearing into the wheel E is the pinion K on theshort shaft B to which is attached the crank L.

The operation is as follows: Power is communicated to the apparatns byturning the crank L in the direction of the arrow, which revolves thepinion K, fast on the shaft B which in turn revolves the loose wheel Eand its connected pinion 9.' This pinion gears into the wheel E on theshaft B, which has the pin: ion g' attached thereto, also loose andrevolving on the sha-ft. The pinion g' gear'sinto the wheel E', which isfast on the shaft B 'Thus motion is imparted to the wheel F, fast onsaid shaft B', and from thence communieated to the wheel F', (into whichit gears,) fast on theshaft B. The motion imparted to the shafts BB'through the above-n1entioned train of gear- 9 wheels and ntermedatescauses said shafts to ing secured to thearbors I, fast on the shafts BB, by means of the bolts 72 the outer ends ;tre Secured to the sides y yof the case A by the bolts h'. The expensive power of the series ofcoiled springs imparted thereto by the train of winding-gear, whichcoils the springs down tightly upon their arbors, then causes the saidshafts B B' to commence revolving in the opposite direction to whichthey were rotated during the winding operation, and carries the wheel (3held fast on the shaft B' by its pztwl-connection with the ratehet-wheelD, with said shztft B', and inparts motion to the pinion Z and wheel C,connected together,but loose on the shaft B. The wheel C in turn engageswith the pinion b on shaft B', which is connected with wheel C', thatgears into pinion b', which is fast to wheel C'. This wheel in turngearsinto pinion b*, connected to wheel 0 which engages with pinion bandrevolves the grooved wheel Ceonnected with last-mentioned pinion. Anendless belt, io communicate with nachinery to which rotary notion isdesired to be Lpplied,1-uns in the groove of wheel C This wheel G' maybe a, toothed wheel, and gear with another of equal size or into apinion, to impart motion, if desired. By this arrangement of gear-wheelsand intermediate pinions upon two shafts, in connection with theexpensive or resilient force of the coiled springs, a rapid notion ismparted to the grooved wheel C, and from thence to nachinery desired tobe rotated.

Having thus described our improvement in spring-motors, what we desireto secure and claim by Letters Patentisl. The series of coiled springsG, having their inner ends Secured to the arbors I on the shafts B B'and their outer ends to the case A, in eonbination with the train ofgearwheels G to C and pinions I to b onsaid shafts B B', the wheels andpinions so arranged and engaging with each other as to impart rapidrotary n otion and power to the grooved wheel C by means of theresilient force of the springs G, substantially in the manner and forthe purpose specified.

2. The eombination of the pinion K on the Shtfl B, the train ofgear-wheels E E' E" FF', and pinionsg g' on the shafts B B', andratehet-wheel D. for coiling the springs Gr on the arbors I oi' saidshafts, substantially as described.

3. The eonbination, with the case A, of the series ot" springs G, andtrains of Operating and winding gearin g upon two shefts that have theirbearings in the ends of said case,to form a motor for Operatingnaehinery, substantially as hereiu set forth.
